Thirdly, in lung cancer RBM10 is highly expressed [10], but while in our A549, HeLa, BEAS-2B and GLC20 cells transcripts encoding both RBM10v1 isoforms were observed, there was two-fold more RBM10v1(V354del) than RBM10v1(V354) in the GLC20 SCLC cells. This evidence concerns the gene RBM10 and small cell lung carcinoma.
